About Heat Pumps

Heat pumps provide both heating and cooling by moving heat rather than generating it. In cooling mode, they work like air conditioners, moving heat outside. In heating mode, the process reverses, extracting heat from outdoor air and bringing it inside. This technology is highly efficient in mild climates like the Bay Area, offering significant energy savings over traditional heating.

How It Works

Heat pumps use refrigerant to transfer heat between indoor and outdoor coils. A reversing valve changes the direction of refrigerant flow between heating and cooling modes. In heating mode, the outdoor coil absorbs heat from outside air (even in cool weather) and the indoor coil releases it inside. The compressor provides the energy to move heat against the temperature gradient.
